航空学报是世界范围内享有盛誉的学术期刊，它以发布高质量的航空航天科学与工程领域的论文而闻名。在投稿给航空学报时，如何写好论文摘要是非常重要的一步。本文将介绍航空学报论文摘要的写作方法，并提供一些范例以供参考。

首先，航空学报论文摘要的写作方法有一些共同之处，无论是什么类型的研究论文。一个好的摘要应该包含以下几个要素：

1. 引出研究背景：首先要简明扼要地介绍该论文研究的背景和意义，即为什么要进行这项研究。

2. 阐述研究目的：明确说明研究的目的和研究问题，即想要解决的具体科学问题。

3. 方法和材料：简要描述研究所采用的方法和所用的材料，包括实验设计、数据采集和分析方法等。

4. 研究结果与发现：总结研究的主要结果和发现，可以包括具体的数据和图表。

5. 讨论和结论：对研究结果进行分析和解释，并给出相应的讨论和结论，突出研究的创新性和贡献。

Title: Experimental Investigation of Wingtip Vortex Effect on Aerodynamic Performance of Aircraft Wing

Abstract: This paper presents an experimental investigation on the effect of wingtip vortex on the aerodynamic performance of aircraft wing. The study aimed to understand the formation and behavior of wingtip vortex and its impact on lift and drag characteristics of the wing. The wind tunnel experiment was conducted using a scaled-down model of an aircraft wing with various wingtip designs. The lift and drag forces were measured at different angles of attack and wingtip configurations. The results showed that the presence of wingtip vortex significantly affects the lift and drag of the wing. The wingtip with a winglet design effectively reduced the wingtip vortex and improved the overall aerodynamic performance of the wing. This study provides valuable insights into the design and optimization of aircraft wingtip for improved aerodynamic performance.

范例2：

Title: Numerical Simulation of Supersonic Flow over a Delta Wing with Leading Edge Serrations

Abstract: In this study, a numerical simulation was conducted to investigate the effect of leading edge serrations on supersonic flow over a delta wing. The serrations, designed to control shock-induced boundary layer separation, were systematically varied in terms of depth and wavelength. The computational fluid dynamics (CFD) analysis was performed using a compressible turbulent Navier-Stokes solver. The results showed that the leading edge serrations effectively delayed shock-induced boundary layer separation, resulting in improved lift-to-drag ratio and reduced drag. The maximum drag reduction was observed at a depth of 3% chord length and a wavelength of 5% chord length. This study demonstrates the potential of leading edge serrations in enhancing the aerodynamic performance of supersonic delta wings.

以上是两个不同类型的航空学报论文摘要范例，分别涉及了研究背景、目的、方法、结果和结论等关键要素。当写作航空学报论文摘要时，作者应该确保简明扼要地介绍自己的研究工作并突出其创新性和科学价值。同时，要注意使用简练的语言和科学术语，并避免使用太多的技术细节。通过遵循上述的写作方法和范例，作者可以为自己的论文摘要增添更多的内容，使其更具丰富性和发表潜力。
